I've had my 18sw115-8 smell funny when strapped one per side off my pxm-1450, however they can clip a little and still the driver seem okay.

I've also tried two at one side and it seemed to work fine however that was for a short period in the store and no drivers on the other channel.

Question:, if you have high crest factor music, would you benefit more from the increased headroom from the 4r driver strapped one a side compared to if you play low crest factor music?

Mine can give 130 volts but they start to clip barely(doesn't sound bad tho) when the limiter is set at around 95v with a crestfactor of 3.5-4.5 with my drivers.

No point starting new thread...

So could UK resellers clear up few things.

So potential buyer should look for original MK1 or one from the new company/stock?

Bee, I guess that's what you are supplying now?

We are already using and sold substantial number of the new onese. They beat SAE in quality.
If you have trouble finding any, we can sort you out.

Any chance of some internal Screenshots?

What current rating is the breaker on new models?

Any power consumption figures for 4 ohm stereo, at various freqs?

Ill check for the pictures. 
No data at this moment about the consumption.
The amp is 2x1600W/8ohm and 2600W/4 ohm.
2.66ohm operation without any problem. 2 ohm stable, but we have not made any long term test in real condition yet for 2ohm load.
